Angularjs 如果本地项目中存在节点_模块，则Docker compose生成失败

我试图理解docker/docker compose的基础知识，所以我开始了自己的教学实验。基本上，我想测试以下的整个周期：在本地开发代码，编写docker和docker compose文件，推送到github repo，在测试目录中克隆repo，docker compose up-build并观察神奇之处。 为了测试所有这些，我使用了我已经编写的Angular应用程序。docker文件如下所示：

# base image
FROM node:10.13.0-jessie

# set working directory
RUN mkdir /usr/src/app
WORKDIR /usr/src/app

# add `/usr/src/app/node_modules/.bin` to $PATH
ENV PATH /usr/src/app/node_modules/.bin:$PATH

# install and cache app dependencies
COPY package.json /usr/src/app/package.json
RUN npm install
RUN npm install -g @angular/cli

# add app
COPY . /usr/src/app

# expose port
EXPOSE 4200

# start app
CMD ng serve --host 0.0.0.0

Docker-compose.yml是：

version: '3.7'

services:
  myapp-frontend:
    container_name: frontend
    build: ./
    working_dir: /usr/src/app
    command: ng serve --host 0.0.0.0
    ports:
      - "4200:4200"

因此，除非我决定开始在测试文件夹上开发，否则一切都会按预期进行。在这种情况下，如果我再次尝试docker compose up-build，则在执行npm安装以下载所有node_模块后，构建将失败，并出现以下错误

Traceback (most recent call last):
  File "site-packages\docker\utils\build.py", line 96, in create_archive
OSError: [Errno 22] Invalid argument: 'path\\myapp-frontend\\node_modules \\.bin\\acorn'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "docker-compose", line 6, in <module>
  File "compose\cli\main.py", line 71, in main
  File "compose\cli\main.py", line 127, in perform_command

据我所知，Angular应用程序的整个构建部分都发生在容器中，事实上，当我克隆repo时docker compose可以正常工作，那么为什么它突然关心本地OS项目中的node_模块呢

我真的不知道这种行为的原因，但您不应该在内部复制node_模块。见下面的评论

# install and cache app dependencies, **OK**
COPY package.json /usr/src/app/package.json
RUN npm install
RUN npm install -g @angular/cli

# add app, **this also copies your local node_modules, overwriting previously installed**
COPY . /usr/src/app

因此，您可以通过添加.dockrignore文件来解决此问题

尝试进入源映像内部，运行它即可

docker run --rm -it node:10.13.0-jessie bash

然后一步一步地尝试您的命令，调试并完全控制它。然后将工作内容添加到Dockerfile中

要将数据复制到正在运行的容器，请使用

docker cp package.json mycontainer:/usr/src/app/package.json

docker cp package.json mycontainer:/usr/src/app/package.json
